Title: Ocular plug for punctal and intracanalicular implants
Inventor: ZHOU STEPHEN Q
IPC: A61F2/14
Filed: 2000-08-04
Abstract: An ocular plug design and method of insertion is described for the treatment of dry eye. This ocular plug is a narrow rod-like cylinder of appropriate diameter, which is tapered at one end, for insertion into an ocular channel.  The plug is prepared from either (or both) of two specific classes of polymeric materials having both viscous and elastic properties. The first class of polymeric materials have a glass transition temperature (Tg) at or below human body temperature (37 ~C). The second class of polymeric materials have a melting temperature (Tm) at or below human body temperature (37 ~C).  The plug is stored in a frozen, rigid, elongated state prior to insertion into an ocular channel. Once inserted into an ocular channel, the smart plug responds to an increase in temperature, due to the surrounding physiochemical environment, whereby it becomes soft and the plug subsequently expands to adapt to the size and shape of the patient's punctum or canaliculum. Once the plug expands to the size of the particular ocular channel, the plug is met with a resistance from the surrounding tissue. At this point, expansion of the plug ceases and the plug can effectively block tear drainage through either ocular channel.

Title: Neutralisation of landmines using high-power microwaves
Inventor: BERGERON DENIS M
IPC: F41H11/12
Filed: 2003-04-30
Abstract: An apparatus to neutralize landmines using high power microwaves has a blast hardened dish antenna mounted on a vehicle along with a microwave generator and power generator.      A waveguide from the microwave generator feeds microwaves to a feed horn for the antenna. Plugs that are transparent to microwaves are located in the waveguide to prevent the blast wave generated by a detonated landmine from propagating inside of the waveguide and damaging the microwave generator.      Flexible sections in the waveguide dampen any shock wave produced by a detonated mine from traveling along the waveguide towards the microwave generator.

Title: Spectrometre de masse
Inventor: WEST MARC B A
IPC: G01N27/62
Filed: 2002-05-03
Abstract: L'invention porte sur un nouveau spectromètre (10) dans lequel les molécules d'échantillons (26) étant ionisées oscillent sous l'effet de la réflexion de champs électriques créés entre deux électrodes (12, 14) dans une chambre à vide (20). Une électrode grille (16) de production d'électrons située entre les électrodes réflectrices (12, 14) produit des électrons par émission secondaire à chaque course des ions oscillants lorsque certain d'entre eux frappent la grille de l'électrode. On détecte (18) les électrons secondaires après leur passage à travers l'électrode réflectrice. La fréquence d'oscillation des ions dépend de leur masse et de la distribution en fréquence des signaux de chaque événement de production d'électron; il est ainsi possible d'identifier les ions de différentes masses. L'invention permet de réaliser des spectromètres beaucoup plus compacts que les spectromètres de masse à temps de vol, et moins chers que les spectromètres de masse à transformé de Fourier à résonance cyclotron des ions.
